Aviditi 30404PCMC 4-Piece Mirror Boxes, 30" L x 40" W x 3 1/2" H, Kraft (1 Set of 4 Pieces))

These work great for protecting your mirrors or artwork. Packing up to move across country. I did also purchase some foam corner protectors and shrink wrapped my items before placing them in the box. It’s good that they’re adjustable so they fit more sizes. They were really easy to assemble takes more taping and patience then just placing them in a non adjustable box but if your like me you have varied sizes of artwork. Just wish they were less expensive as I need to buy more .

It states it's 4 pieces, and a 4 pack. To me, that says it's 4 boxes. Instead it's 1 box. Terrible value for the money,

A clever way to pack picture frames of assorted sizes. Easy to use. Requires sufficient tape to work properly. Shipped framed artwork coast-to-coast via UPS, and items arrived undamaged. Use foam corner guards and bubble wrap around frames for extra protection when shipping. Highly recommended.

Mirror boxes were used to wrap pictures, which was perfect.

It was very easy to assemble. Do not tape until completely assembled and aligned on all 4 sides. This was a very large mirror and after taping the 4 sections together, it was very sturdy!

It worked, but the 4 pieces required a lot of tape to secure.

Purchased to protect a very expensive leaded glass hanging suncatcher. Was easy to use with simple instructions. Was loaded in our POD as it traveled from Hawaii to Florida. Checked it upon receipt, and the travel was excellent.

Thin, poorly designed packaging box. This product is little more than paper and will not protect glass or mirrors. For the price, I expected much more. Avoid this purchase!
